• The appliance requires an independent power supply of proper capacity. See the
nameplate for electrical specifications. Failure to use an independent power supply
of proper capacity can result in a tripped breaker, blown fuse, damage to existing
wiring, or component failure. This could lead to heat generation or fire.
• THE APPLIANCE MUST BE GROUNDED. The appliance is equipped with a
NEMA 5-15 three‑prong grounding plug
to reduce the risk of potential shock
hazards. It must be plugged into a properly grounded, independent 3-prong wall
outlet. If the outlet is a 2-prong outlet, it is your personal responsibility to have a
qualified electrician replace it with a properly grounded, independent 3-prong wall
outlet. Do not remove the ground prong from the power cord and do not use an
adapter plug. Failure to follow these instructions may result in death, electric shock,
or fire.
• Do not use an extension cord.
• Do not use an appliance with a damaged power cord. The power cord should not
be altered, jerked, bundled, weighed down, pinched, or tangled. Such actions could
result in electric shock or fire. To unplug the appliance, be sure to pull the plug, not
the cord, and do not jerk the cord.
4
WARNING, continued
• The GREEN ground wire in the factory-installed power cord is connected to the
appliance. If it becomes necessary to remove or replace the power cord, be sure to
connect the power cord's ground wire.
• Do not splash, pour, or spray water directly onto or into the appliance. This might
cause short circuit, electric shock, corrosion, or failure.
• Do not make any alterations to the appliance. Alterations could result in electric
shock, injury, fire, or damage to the appliance.
• The appliance is not intended for use by persons (including children) with reduced
physical, sensory, or mental capabilities, or lack of experience and knowledge,
unless they have been given supervision or instruction concerning use of the
appliance by a person responsible for their safety.
• Children should be properly supervised around the appliance.
• Do not climb, stand, or hang on the appliance or doors/drawers or allow children or
animals to do so. Do not climb into the appliance or allow children or animals to do
so. Death or serious injury could occur or the appliance could be damaged.
• Be careful not to pinch fingers when opening and closing the doors/drawers or rail
cover (prep table models) or when handling food pans. Be careful when opening
and closing the doors/drawers or rail cover when children are in the area.
• Open and close the doors/drawers and rail cover (prep table models) with care.
Opening the doors/drawers or rail cover too quickly or forcefully may cause injury
or damage to the appliance or surrounding equipment.
• Do not use combustible spray or place volatile or flammable substances in or near
the appliance. They might catch fire.
• Keep the area around the appliance clean. Dirt, dust, or insects in the appliance
could cause harm to individuals or damage to the equipment.
• Do not throw anything onto the shelves or load any single shelf with more than
120 lb. (54.5 kg) of product. They might fall off and cause injury.
• Do not load any single drawer with more than 75 lb. (34 kg) of product. Depending
on the weight of product in the drawers, secure the unit as necessary to prevent it
from overturning. Do not open more than one drawer at a time.
• The appliance is designed only for temporary storage of food. Employ sanitary
methods. Use for any other purposes (for example, storage of chemicals or
medical supplies such as vaccine and serum) could cause deterioration of stored
items.
• Do not block air inlets or outlets, otherwise cooling performance may be reduced.
• Do not tightly pack the cabinet. Allow some space between items to ensure good
air flow. Also allow space between items and interior surfaces.
• Do not put warm or hot foods in the cabinet. Let them cool first, or they will raise
the cabinet temperature and could deteriorate other foods in the cabinet or
overload the appliance.
5
WARNING, continued
• All foods should be wrapped in plastic film or stored in sealed containers. Otherwise
foods may dry up, pass their smells onto other foods, cause frost to develop, result
in poor appliance performance, or increase the likelihood of cross‑contamination.
Certain dressings and food ingredients, if not stored in sealed containers, may
accelerate corrosion of the evaporator, resulting in failure.
• Do not store items near air outlets. Otherwise, items may freeze up and crack or
break causing a risk of injury or contamination of other food.
Additional Warnings for Prep Table Models
• The entire rail must always be covered by rail dividers and pans (1/6 size, up to
6" (15 cm) deep). Otherwise, the appliance will not cool properly.

the cabinet temperature and could deteriorate other foods in the cabinet or
overload the appliance.
• All foods should be wrapped in plastic film or stored in sealed containers. Otherwise
foods may dry up, pass their smells onto other foods, cause frost to develop, result
in poor appliance performance, or increase the likelihood of cross‑contamination.
Certain dressings and food ingredients, if not stored in sealed containers, may
accelerate corrosion of the evaporator, resulting in failure.
• Do not store items near air outlets. Otherwise, items may freeze up and crack or
break causing a risk of injury or contamination of other food.
Additional Warnings for Prep Table Models
• The entire rail must always be covered by rail dividers and pans (1/6 size, up to
6" (15 cm) deep). Otherwise, the appliance will not cool properly.
• Use only 1/6 size pans up to 6" (15 cm) deep. Do not use damaged pans.
• Ingredients must be pre-chilled to 37°F (3°C) or less before placing in rail.
• Keep the rail cover closed when not actively preparing food.
• The rail is for keeping ingredients cool while preparing food. If not actively preparing
food for a long period such as overnight, seal pans with plastic wrap in addition
to closing the rail cover. Depending on conditions, the cabinet temperature
setting may need to be adjusted to prevent items from freezing. Alternatively, seal

D. Defrost
1. Undercounter and Worktop Refrigerators
Off-Cycle Defrost: Undercounter and worktop refrigerators defrost naturally between run
cycles.
2. Prep Table Refrigerators and Undercounter and Worktop Freezers
Prep tables and freezers use a heated, time-initiated, temperature-terminated defrost.
• Prep tables and freezers have a defrost interval of 6 hours. The defrost timer starts
when power is supplied to the appliance.
The minimum defrost time is 5 min.
The maximum defrost time is 25 min. for prep tables and 1 hour for freezers.
• When the defrost thermistor warms to 44°F (6.7°C) on prep tables and 45°F (7.2°C)
on freezers, defrost terminates.
• On prep tables, the compressor energizes 1-min. after defrost heater de-energizes
(drip time) and the evaporator fan motor(s) energize 30-sec. after the compressor
energizes. Note that the 30‑sec. evaporator fan motor delay time is a maximum;
if the defrost thermistor cools to 40°F (4.4°C) before the 30‑sec. evaporator fan
motor delay timer terminates, the evaporator fan motor(s) will energize.
• On freezers, the compressor energizes 3-min. after defrost heater de-energizes
(drip time) and the evaporator fan motor(s) energize 5-min. after the compressor
energizes. Note that the 5‑min. evaporator fan motor delay time is a maximum; if the
defrost thermistor cools to 25°F (-3.8°C) before the 5-min. evaporator fan motor
delay timer terminates, the evaporator fan motor(s) will energize.
To manually initiate or terminate a defrost cycle: Turn the cabinet temperature control
dial to 7, pause for 3 to 10 sec., then return the cabinet temperature control dial to any
position below 7. Defrost initiates or terminates within 5 sec.
Note: When defrost is manually initiated it continues through the normal defrost cycle
unless manually terminated.

F. Safety Devices
1. Compressor External or Internal Protector
If combined temperature/amperage value is above the limit specified by the
compressor manufacturer, the compressor protector operates independently to turn
off the compressor. The compressor protector de-energizes the compressor until the
temperature/amperage value returns to an acceptable level.
2. High-Pressure Switch (CRMF48(-W), CRMF60)
If pressure on the high-side of the unit exceeds Hoshizaki specifications, the
high‑pressure switch activates and interrupts the compressor circuit, de‑energizing the
compressor until the pressure returns to an acceptable level.
23
